Now Minnesota defensive end Jared Allen has to show he can get sacks against somebody other than the Green Bay Packers. Allen, the former Chiefs star, leads the NFL with 10 1/2 sacks, although 7 1/2 of them have come in two games against the Packers. At the halfway point of the season, it&rsquo;s not unrealistic to start projecting Allen with not only his first 20-sack season, but he&rsquo;s got a chance to break Michael Strahan&rsquo;s NFL-record 22 1/2 sacks set in 2001.
